Accessory Drive Belt Guide for the 1959 Studebaker 4E2 Truck
Keep your classic Studebaker V8 running cool and charging strong with the right V-belt.
- A modern aftermarket belt from a brand like Gates or Continental is more reliable than a 65-year-old original part.
- A squealing noise is the first warning sign of a failing belt; inspect it immediately to prevent being stranded.
- A broken belt will cause the engine to overheat and the battery to stop charging, making the truck undrivable.
- Replacement is a simple DIY task that requires only basic tools and knowledge of how to properly tension the belt.
Is Your Studebaker's Belt Trying to Tell You Something?
A failing V-belt on a classic truck like the 4E2 provides clear warning signs. Because it runs critical components, you should address these symptoms immediately to avoid being stranded or causing engine damage.
- Squealing Noises: The most common symptom is a high-pitched squeal, especially when you start the engine or accelerate. This is caused by the belt slipping on the pulleys due to wear, incorrect tension, or contamination from oil or coolant.
- Visible Wear and Damage: A quick visual inspection can tell you a lot. Look for cracks, fraying, missing chunks, or a shiny, glazed surface on the sides of the belt. Old rubber becomes brittle and is a sure sign that replacement is needed.
- Charging System Issues: If the belt is slipping, it cannot turn the generator fast enough to charge the battery. You might notice the "GEN" light on your dashboard glowing, or your headlights may appear dim.
- Engine Overheating: A slipping or broken belt will not turn the water pump properly, causing the engine's temperature to rise quickly. This is a critical failure that requires you to shut off the engine immediately to prevent severe damage.
Choosing the Right Aftermarket Belt: OEM vs. Aftermarket
For a vintage truck, the choice between OEM and aftermarket is simple. Original Studebaker-branded belts are no longer made. While you might find a "New Old Stock" (NOS) belt online, a 65-year-old piece of rubber is not a reliable part for a working truck. Rubber degrades over time, regardless of use, becoming brittle and prone to failure.
Modern aftermarket belts from reputable brands are made with superior rubber compounds that are far more resistant to heat, oil, and cracking than the originals. For a 1959 Studebaker 4E2, a new aftermarket belt is a significant upgrade in durability and reliability.
Brand Quality Comparison
| Brand Tier | Our Assessment |
|---|---|
| Best / Preferred: Gates | Gates is a top-tier brand frequently preferred by professional mechanics for classic and heavy-duty vehicles. They are known for excellent durability and precise fit, making them an ideal choice for the 4E2. |
| Excellent: Continental | Continental is a major OEM supplier and a top name in the aftermarket, known for quiet, long-lasting belts. Their V-belts are high-quality and a very reliable option for your Studebaker. |
Pro Tip: For a simple V-belt system, correct fitment (length and width) and proper tension are more important than the brand choice between these two excellent options. Always check your pulleys for cleanliness and damage before installing a new belt.

Frequently Asked Questions (FAQ)
Is it hard to replace the accessory drive belt myself?
No, this is a very easy job for a DIYer on a 1959 Studebaker. The process involves loosening the mounting bolts on the generator, pivoting it to create slack, swapping the old belt for the new one, and then applying tension to the belt while tightening the generator bolts. It requires only basic hand tools.
How do I know if the new belt has the right tension?
Proper tension is critical. If it's too tight, it can damage the bearings in your generator or water pump. If it's too loose, it will slip and squeal. A good rule of thumb for V-belts is to press on the belt at its longest point between pulleys; you should have about half an inch of deflection. You should also be able to twist the belt about 90 degrees (a quarter turn) with your fingers, but not more.
Why is my new belt squealing?
The most common reason for a new belt to squeal is incorrect tension, it's probably too loose. It could also be caused by oil or coolant residue on the pulleys. Always clean the pulleys before installing a new belt. Worn or misaligned pulleys can also cause noise.
Are there any recalls for the accessory drive belt on my truck?
No. There are no recalls or Technical Service Bulletins (TSBs) for this part on a 1959 Studebaker. The vehicle predates the modern NHTSA recall system, and any issues you encounter will be due to normal wear and tear on this simple mechanical system.
Technical Specifications
The 1959 Studebaker 4E2 uses a V-belt system, not a modern serpentine belt. There may be more than one belt if the truck is equipped with optional accessories. The key specifications are the belt's top width and its outside circumference. These dimensions must be matched precisely for the belt to function correctly and have a long service life.
